Can someone explain what i did wrong on 7 and 8

7)  m∠EDC = 61°

8)  FB = 13

Step-by-step explanation:

In number 7 the figure is a rhombus

∴ The diagonals bisects the vertex angles and every two opposite angles are equal

∵m∠ABC = 122°

∴m∠ADC = 122° opposite angles

∵BD bisects angle ADC

∴m∠EDC = 122 ÷ 2 = 61°

In number 8

∵ABCD is a rectangle

∴ its diagonals equal and bisect each other

∵AC = 26

∴BD = 26

∵F is the mid-point of AC and BD

∴FB = 26 ÷ 2 = 13
